I reformatted my Win "C" drive and loaded Ubuntu 11.04. The second internal HD of course is not read. It is shown in 'disk utility'. I try to mount it in disk utility but I get an error message
error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sda1 is already mounted on /
One problem I see is the error relates to sda1, but I am trying to mount sdb.
Unfortunately, I am windows literate and ignorant of the coding for linux.
Can someone help me with the code to mount my second drive (sdb)

Hi,
So I'm currently working for with using SecondString for fuzzy string matching, where I have a large dictionary to compare to (with each entry in the dictionary has an associated non-unique identifier). I am currently using a hashMap to store this dictionary.
When I want to do fuzzy string matching, I first check to see if the string is in the hashMap and then I iterate through all of the other potential keys, calculating the string similarity and storing the k,v pair/s with the highest similarity. Depending on which dictionary I am using this can take a long time ( 12330 - 1800035 entries ). Is there any way to speed this up or make it faster? I am currently writing a memoization function/table as a way of speeding this up, but can anyone else think of a better way to improve the speed of this? Maybe a different structure or something else I'm missing.
Many thanks in advance,
Nathan

Is it possible DHCP client check the contents of an option ?
I need provisioning a Linux server with DHCP option 140 (option-140).
But the server behaves as if the DHCP did not contain the information.
In the file /var/lib/dhcp/dhclient.eth0.leases
I do not see advanced DHCP options (option-140, option-141, option-142).
How can I manually request the DHCP server to give me the contents of an option (to control the content) ?
Bests Regards,
Nathan

I have a machine running Ubuntu 11.10 Server acting as a Samba server to share my home directory. Everything works fine on my Windows 7 machine, but on my Fedora 16 laptop, if I use Nautilus to try to access the share using smb://192.168.0.8/nathan in the location bar, it just has the loading cursor and does nothing. It never shows any errors, nothing. Using smbclient works just fine, but I'd like to get it working in Nautilus.
I know that there can be problems with SELinux and Samba, so I created a file called booleans.local that contains samba_enable_home_dirs=1.

My C++ application embeds the Python interpreter, but seems to be having some trouble when it shuts down. Right after the main window closes, I get a segmentation fault (this is Windows, but we'll call it a segmentation fault anyway). The stack trace is below:

I'm testing Tokyo Tyrant in a master-master setup and have found the ulog grows out of control and locks up the disk.
At first I found the -ulim option useful and limited the logfile size, however it simply rolls over to a new log, leaving the old ones to clutter up the partition.
I suppose I'll write a shell script that will delete ulogs older than X, once I find out how far back Tokyo Tyrant needs in the update log in order to failover.
Does anyone have any experience with this Tokyo Tyrant? Do you have a feel (acknowledging that every install is different based on what is being stored) for the optimal ulog size vs how far back a Tokyo Tyrant instance needs to look in the ulog to assume master status?
Thanks,
nathan

Hi all,
I moved my hard drive from my Lenovo laptop into my Asus Eee PC netbook. When I started the netbook, after POST all I got was a black screen with a cursor in the upper left corner.
I thought that the migration should work OK because this was a 32-bit version of Windows XP, and the Atom processor in the Asus should support the x86 instruction set. However, I don't know much about Windows, so maybe this was a dumb thought.
I did verify that the BIOS can find the drive.
It required major surgery to replace the drive, so any solution requiring me to remove the transplant drive is not going to fly.
Keeping in mind that the netbook has no optical drive and that I have no other Windows computers (all my other computers run Linux), is there any way I can fix this problem?
Thanks!
Nathan

I have an Asus Eee PC netbook which I upgraded the drive of. After some shenanigans, I was able to do a repair install from my Windows XP CD. However, I still have a blinking cursor in the upper-left-hand corner after POST.
I tried going into the recovery console and doing chkdsk/fixboot/fixmbr with no effect.
Any suggestions would be appreciated!
(Sorry if it's inappropriate to post a followup as a new question; I'm not sure how I should do it in a way that will cause it to actually be seen).
Thanks,
Nathan

I have a a Comments table and a Posts table, where a Post has many comments and a comment belongs to a post (i.e. it has a post_id in the table).
How can I efficiently select the last ten Posts that DO NOT have comments.
I can't seem to accomplish this without first selecting all the posts and checking each for a 0 comment count.
Thanks in advance for any help.

Hi,
After search a long time for a performance bug, I read abut denormal foating point values.
I have an Intel Core 2 Duo and I am compiling with gcc, using "-O2".
So what do I do? Can I somehow instruct g++ to avoid denormal values?
If not, can I somehow test if a float is denormal?
Thanks!

I'm using a Nokia N810 running OS 2008 (version 5.2008.43-7; should be the latest). It can see networks up and down the street in my neighborhood and can connect to mine using WEP. I can also connect to free networks at restaurants and the like.
When I bring it into work, it can't see a wireless network ("No connections available"). When I use netstumbler on my laptop I can see a list of several essids showing green connectivity for the network. I know that the network has its essid broadcast, and I know that it's unsecured.
When I run iwlist wlan0 scan, I see several APs with no essid, but I don't see anything with an essid set. I have verified using iwlist that my hardware supports the correct channels and speeds.
I know this isn't a Nokia/mobile forum, but it's running what's basically a Debian kernel. Any suggestions on what to do in this case? I'm really frustrated by this.
Thanks,
Nathan

I've been messing around with the SQLite Designer in Visual Studio 2008 and I have noticed that when I use the generated Insert/Update statements they run extremely slow.
Example: I have a data table with four columns and 5700 rows it took ~5 mins to insert the data into the database table
However, I wrote my own database connection and insert methods using parameters and a single transaction and the same 5700 rows were inserted in under 1 second.
Why is the generated code so slow and what is benefit to even using it?
Thanks.

Hello,
I'm currently learning Flash (CS4, AS3) and am creating a game. I have currently 1 flv file with 4 scenes, I then move from left to right and then to scene 2 and go from left to right. This is the game where items pop up that need to be clicked on and you get points.
Is there any way I can combine these onto 1 scene? Flash only allows you to have a maximum of 2880px wide. The reason for this is the transition between the scenes is RUBBISH and that my AS is not working correctly in between scenes (it loses values).
Any help would be greatly appreciated!

In a custom DataMapper setter, I'd like to check whether the value I'm setting is valid or not.
For instance:
class ToastMitten
include DataMapper::Resource
property :id, Serial
property :wearer, Enum['Chuck Norris', 'Jon Skeet']
property :first_worn_at, DateTime
def wearer=(name)
super
if wearer.valid? # How can I do this?
first_worn_at = Time.now
end
end
end
t = ToastMitten.new
t.wearer = 'Nathan Long' # invalid value; do NOT set first_worn_at
t.wearer = 'Jon Skeet' # valid value; set first_worn_at
Can I check the validity of a single property like this without calling valid? on the object itself and looking through all the errors?

For a grouped product, I would like to display a link to the simple products it is composed of. For example, if I have a grouped product called Dining Set composed of plates, knives, forks, etc. I'd like each of the subproducts to have a link to that subproduct (click plates goes to the Simple Product for plates)
<?php foreach ($_associatedProducts as $_item): ?>
<tr>
<td><?php echo $this->htmlEscape($_item->getName()) ?></td>
<td class="a-right">
<?php echo $this->getPriceHtml($_item, true) ?>
</td>
<?php if ($_product->isSaleable()): ?>
<td class="a-center">
<?php if ($_item->isSaleable()) : ?>
<a href="<?php $_item->getProductUrl() ?>">View</a>
<?php else: ?>
<p class="availability"><span class="out-of-stock"><?php echo $this->__('Out of stock.') ?></span></p>
<?php endif; ?>
</td>
<?php endif; ?>
</tr>
<?php endforeach; ?>
This is a code snippet from the grouped.phtml file in app/design/frontend/blank/default/template/catalog/product/view/type/grouped.phtml
In particular the line that has $_item-getProductUrl()
This does not work, and I don't know the code needed to get the url for this associated product item. If anyone could help here it would be much appreciated.
Also, where on earth can I find the method's available (and how they're used) for Products or Categories or $_item and the like?
Thanks,
Nathan

I've been trying to solve a problem for a few weeks now. I am running rspec tests for my Rails app, and they are working fine except for one error that I can't seem get my head around.
I am using MySQL with the InnoDB engine.
I have set config.use_transactional_fixtures = true in spec_helper.rb
I load my test fixtures manually with the command rake spec:db:fixtures:load.
The rspec test is being written for a BackgrounDRb worker, and it is testing that a record can have its state updated (through the state_machine gem).
Here is my problem:
I have a model called Listings. The rspec test calls the update_sold_items method within a file called listing_worker.rb.
This method calls listing.sell for a particular record, which sets the listing record's 'state' column to 'sold'.
So far, this is all working fine, but when the update_sold_items method finishes, my rspec test fails here:
listing = Listing.find_by_listing_id(listing_id)
listing.state.should == "sold"
expected: "sold",
got: "current" (using ==)
I've been trying to track down why the state change is not persisting, but am pretty much lost. Here is the result of some debugging code that I placed in the update_sold_items method during the test:
pp listing.state # => "current"
listing.sell!
listing.save!
pp listing.state # => "sold"
listing.reload
pp listing.state # => "current"
I cannot understand why it saves perfectly fine, but then reverts back to the original record whenever I call reload, or Listing.find etc.
Thanks for reading this, and please ask any questions if I haven't given enough information.
Thanks for your help,
Nathan B
P.S. I don't have a problem creating new records for other classes, and testing those records. It only seems to be a problem when I am updating records that already exist in the database.

I've been trying to get a good grounding with Regular Expressions, and am looking for a single book to do so. I've been going through Amazon.com's listings on this subject, and I've identified a few possibilities, but am unsure which would be best for a C# developer who can write very simple Regexs, but wants to learn more. On a scale of 0-9 where 0 is knowing how to spell "Regex" but nothing else, and 9 where I could write a book on the subject out of my own head, I would place myself at 2. Which of the following would be your choice:
Mastering Regular Expressions by Jeffrey E F Friedl
Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan
Sams Teach Yourself Regular Expressions in 10 Minutes by Ben Forta
Beginning Regular Expressions (Programmer to Programmer) by Andrew Watt
Regular Expression Recipes for Windows Developers: A Problem-Solution Approach by Nathan A. Good
Regular Expression Recipes: A Problem-Solution Approach by Nathan A. Good
Now, according to Amazon, "Regular Expressions Cookbook" (REC) above is rated the highest according to user ratings, but only based on 20 reviews. The first one, "Mastering Regular Expressions" (MRE) is rated second based on 140 reviews. This alone suggests that MRE might be by far the best one. But is it best for a relative beginner? Would I perhaps be better getting "Beginning Regular Expressions" (BRE) instead, to start with?
Please help me resolve my confusion!

I've noticed in almost everything I've read so far that the term "clip space" is prepended with the word "homogeneous". Now I understand that it roughly means "all the same", but I don't understand why there is the express need to say "homogeneous clip space". When is clip space not homogeneous and why do we need to differentiate? And for that matter, what exactly does it mean that we're calling it "homogeneous clip space"? Homogenous in relation to what? In what way are the vertices "all the same"?

At work, we've just started on a heavily Javascript based application (actually using Coffeescript, but still), of which I've been implementing an automated test system using JsTestDriver and fabric.
We've never written something with this much Javascript, so up until now we've never done any Javascript testing. I'm unsure what exactly we should be testing in our unit tests. We've written JQuery plugins for various things, so it's quite obvious that they should be verified for correctness as much as possible with JsTestDriver, but everyone else in my team seems to think that we should be testing the page level Javascript as well.
I don't think we should be testing page level Javascript as unit tests, but instead using a system like Selenium to verify everything works as expected. My main reasoning for this is that at the moment, page level Javascript tests are guaranteed to fail through JsTestDriver, because they're trying to access elements on the DOM that can't possibly exist.
So, what should be unit tested in Javascript?
